Projectile Motion
Summary of Projectile Motion • Treating the vertical motion independently of the horizontal motion, and then combining them to find the trajectory, is the secret. – A horizontal glide combines with a vertical plunge to produce a graceful curve. – The downward gravitational acceleration behaves the same as for any falling object.

Properties of Projectile Motion. Projectile motion is the motion of an object thrown (projected) into the air. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory.As an object travels through the air, it encounters a frictional force that slows its motion called air resistance.

A projectile is a particle that is given an initial velocity, but then moves under the action of its weight alone, that is all other forces are ignored. Real objects such as balls and bullets can be modelled as projectiles. The motion of a projectile can be studied by splitting it into two components: horizontal motion and vertical motion.

Once the ball has cleared the barrel of the gun, the force of gravity is responsible for accelerating the ball to the ground. Frictional forces are considered negligible. With this in mind, the motion of the ball can be subdivided into two types: motion in the horizontal direction and motion in the vertical direction. Note that the force
